000245 : The input feature class must have Z values.
Description
The input feature class must already contain z-values prior to using the tool. Feature coordinates can include x,y and x,y,z vertices. Z- values are most commonly used to represent elevations, but they can represent other measurements such as annual rainfall or measures of air quality.
Solution
Switch to a feature class that already uses z-values or create a new one.
